Difficulty: EasyWindows Security Settings and User Account Control

A user logged into a Windows workstation with a standard user account attempts to execute a software installer. Before the installation wizard opens, the screen dims and a dialog box pops up asking for an administrator password to proceed. Which Windows security feature is responsible for displaying this credential prompt?

  1. User Account Control (UAC)Answer
  2. B
    Windows Defender Firewall
  3. C
    Credential Manager
  4. D
    BitLocker Drive Encryption

Answer

User Account Control (UAC) is the Windows security feature that intercepts system-level changes and prompts standard users to enter administrator credentials.
User Account Control (UAC) protects Windows operating systems by preventing unauthorized administrative changes. When a standard user attempts to perform an administrative action, UAC dims the secure desktop and requires administrator credentials to elevate permissions.

Step-by-Step Solution

1
Analyze the observed system behavior in the scenario.
The desktop dims and a dialog box interrupts an installation attempt to request administrative credentials.
This behavior indicates a security boundary check designed to prevent unauthorized application execution or system modifications.
2
Identify the Windows feature responsible for privilege elevation prompts.
User Account Control (UAC) enforces least privilege by forcing applications to run in standard user context until elevated through an explicit admin credential prompt.
UAC protects the operating system from unauthorized changes by requiring authorization before executing administrative actions.
